【摘要】:目的: 超声胃肠充盈造影检查是通过口服超声助显剂将胃肠道充盈以排除气体后直接经腹对胃肠道进行的超声检查项目。目前该检查在全国范围内开展较少,本研究旨在评价超声胃肠充盈造影检查对胃癌TNM分期的诊断价值,,以促进临床对该检查的认知。 材料与方法: 选择经胃镜活检确诊的胃癌患者50例,于术前一周内行胃肠充盈造影超声检查,运用二维超声观察肿瘤的大小、形态、浸润程度以及淋巴结转移情况和有无远处转移,依据2010年国际抗癌联盟/美国癌症联合委员会(UICC/AJCC)制定的TNM分期标准评估胃癌的分期。将评估结果与术后病理分期进行比较,分别计算二者间T分期、N分期、M分期的Kappa值,Kappa≥0.75为一致性较好,0.75>Kappa≥0.04为一致性一般,Kappa<0.4为一致性较差。从而评价超声胃肠充盈造影检查对胃癌TNM分期的诊断价值。本论文中所有数据统计均采用统计学软件SPSS19进行分析。 结果: 超声诊断结果与术后病理分期比较: T1为9例,超声胃肠充盈造影检查明确诊断5例、准确率为55.6%(5/9),另外4例中2例过深诊断为T2、2例过深诊断为T3;T2为11例,超声胃肠充盈造影检查明确诊断6例、准确率为54.5%(6/11),另外5例中4例过深诊断为T3、1例过深诊断为T4;T3为19例,超声胃肠充盈造影检查明确诊断15例、准确率为78.9%(15/19),另外4例过深诊断为T4;T4为11例,超声胃肠充盈造影检查明确诊断10例、准确率为90.9%(10/11),另外1例过浅诊断为T3。超声胃肠充盈造影检查对胃癌浸润深度T分期的总准确率为72%(36/50)。二者间Kappa值为0.608,一致性一般。 N0为13例,超声胃肠充盈造影检查明确诊断10例、准确率为76.9%(10/13),另外3例中1例过深诊断为N1、2例过深诊断为N2;N1为15例,超声胃肠充盈造影检查明确诊断12例、准确率为80%(12/15),另外3例中1例过深诊断为N2、1例过深诊断为N3,1例过浅诊断为N0; N2为16例,超声胃肠充盈造影检查明确诊断13例、准确率为81.3%(13/16),另外3例中2例过深诊断为N3,1例过浅诊断为N1; N3为6例,超声胃肠充盈造影检查明确诊断6例、准确率为100%(6/6)。超声胃肠充盈造影检查对淋巴结转移程度N分期的总准确率为82%(41/50)。二者间Kappa值为0.755,一致性较好。 超声胃肠充盈造影检查对M分期的诊断与病理分期结果完全一致。 结论: 1.超声胃肠充盈造影检查具有检出率高、诊断准确、无痛无创、可重复检查性好的优点。 2.超声胃肠充盈造影检查诊断胃癌T分期的准确率一般。 3.超声胃肠充盈造影检查诊断胃癌N、M分期的准确率较高。 4.超声胃肠充盈造影检查可作为胃癌筛查及术前评估TNM分期的常规检查。
[Abstract]:Objective: ultrasound gastroenterography is a kind of ultrasound examination which fills the gastrointestinal tract with oral ultrasound aids to remove gas and directly through the abdomen. The purpose of this study was to evaluate the diagnostic value of ultrasonography in TNM staging of gastric cancer and to promote the clinical understanding of this examination. Materials and methods: fifty patients with gastric cancer diagnosed by gastroscopy biopsy were examined with Gastrointestinal filling ultrasonography within one week before operation. The size and shape of the tumor were observed by two-dimensional ultrasound. The degree of invasion, lymph node metastasis and distant metastasis were evaluated according to the TNM staging criteria established by the International Union against Cancer / American Cancer Joint Commission (UICC/AJCC) in 2010. The Kappa values of T stage, N stage and M stage were calculated respectively. Kappa 鈮
